My name is Paul Karol and I work as a director in a Russian IT company that mostly sells their products in the international market.

I have been deeply involved in a project and I haven’t had time to write here lately.  

But out of this work came an understanding of two very large Mistakes that are being made that prevent your pre-sales from succeeding. 

I’m going to go into deeper detail on each one of these issues in the next articles, but I will introduce them here now.

Let me make you a promise….. if you correct these two issues, your software and development projects will sell.  

**I have a proven track record. If these areas are fixed the company begins to sell 150 % more than they’ve ever sold in the past. 

150% more profits!

For one of my projects I was exploring Reddit to understand how players create characters in video games, what is important to them in this process, and what their preferences are. It turns out that communities sharing their creations or seeking help with specific character designs remain active even for games released years ago. This realization sparked the idea for a hobby project that could assist these players in creating the characters they envision.

Secret Management and Why It’s Important

Hi! My name is Evgeny, and I work as a Lead DevOps at Exante. In this article, I will discuss the practical experience of setting up a high-availability HashiCorp Vault with a GCP storage backend and auto unseal in Kubernetes (K8s).

Our infrastructure used to consist of thousands of virtual and physical machines hosting our legacy services. Configuration files, including plain-text secrets, were distributed across these machines, both manually and with the help of Chef.

We decided to change the company’s strategy for several reasons: to accelerate code delivery processes, ensure continuous delivery, securely store secrets, and speed up the deployment of new applications and environments.

We decided to transition our product to a cloud-native model, which required us to change our approach to development and infrastructure. This involved refactoring our legacy services, adopting a microservices architecture, deploying services in cloud-based Kubernetes (K8s), and utilizing managed resources like Redis and PostgreSQL.

In our situation, everything needed to change—from applications and infrastructure to how we distribute configs and secrets. We chose Google as our cloud provider and HashiCorp Vault for secret storage. We've since made significant progress on this journey.

Why HashiCorp Vault?

There were several reasons:
